What You Should Know About Testing to a Safety Factor

At Ergodyne, all trapping and tethering solutions are “third-party certified to a 2:1 safety factor.” That’s pretty critical … but you won’t know just how important without first understanding what it actually means.

In the latter stages of product development, we take our tool attachments and lanyards to an independent third-party lab and they test them to make sure they can dynamically handle twice as much weight as the weight rating claims. Their testing methods are specific to the products themselves, and usually involve a succession of weights to gauge a product’s durability.

We do this to ensure a lanyard that has, say, a 10 lb (4.5kg) weight rating, can actually handle up to 20 lbs (9.1kg). Because workers may think a 12 lb (5.4kg) tool actually weighs 10 lbs (4.5kg) and tether it accordingly. If a drop occurs, we don’t want an accident to happen because of that miscalculation by the user.

This was the same process we undertook to test our new tool lanyards.


Product durability may be the most important characteristic when it comes to worker safety. Because workers need to be fully confident in their safety when working at heights.
